Abstract:

In ARO STTR Phase 1 program, we have demonstrated the concept and developed a real-time, two-dimensional THz wave imaging system. The THz imaging system uses electro-optic crystals and is capable of time-domain far-infrared spectroscopy across a frequency range extending from near DC to several THz. We have improved THz imaging spatial resolution by one order. We have designed and started to construct a portable THz beam system for commercial applications. In particular, we have demonstrated the feasibility of using a chirped optical probe pulse to read THz imaging in an electro-optic crystal which provides the measurement of a THz wave with an unprecedented data acquisition rate. We have attracted over 30,000 outside funding for THz research and commercialization. We have established a network with scientists and researchers in THz field.
